l Application ledJuly 16,-1926. Serial No. 122,931.

i This invention relates to andcompreliends an attachment for shears, seissors,'or other fcutting implements of thisnature to afford .means for insuringftlie proper coaction yof vthe shearing edges of the blades.

One `of the principal objects and advantages of the. present invention, is to provide edges 13 of the arms are preferably bowedv an attachment for shears, scissors, or other cutting implements of this nature, which Vwhen applied, positively insures the proper correlationv of the shearing or cuttingl edges irrespective of Whether the same aremanipulated With the right or the left hand.

The invention furthermore aims. to provide an attachment of this character which is extremely simple in its construction, inexpensive to manufacture, and which is read'- ily applicable to or removable from an im-V plement. v Y

` lVith the above recited and other objects in view, referencev is had to the following specification and accompanying drawings in which there is exhibitedcertain examples or embodiments of the invention which are in r no Way intended as limitations upon the scope of the appended claims as it is to be clearly understood that variationsand modifications Which properly fall Within the scope of said claims may be resorted to When found expedient.

In the drawingsy Figure lis a.side"vieW of an implement with the attachment applied;

Fig. 2 is a similar fragmentary vievvV illusr tratiiig the blades vof the implement open;

Fig. 3 is a sectional View taken approximately on the line 3-3 of Fig. 1;

Fig. 4 is a fragmentary edge view of the implement with the attachment applied;

Fig. 5 is a perspective view of an implement with a slightly modified forni of the attachment in applied position Fig. 6 is a similar view of a further modifie-ation.

Referring to the drawings by characters of reference, A indicates generally a pair of shears or scissors including blades B and C which are pivotally connected at D and provided with handles E and F.

The attachment constituting the present invention consists of a strip of resilient material, which is cut, bent and formed tov provide a body 10 of substantially U-shape in cross sectional configuration Lpresenting arms l1 connected by a blght 12. The free voppositely to present the concave portions ctoward eachother, Whilethe bightor Vconnecting portion l2 is medially slotted at`l4.

- In practice, the attachmentispreferably applied with the bight portion ydisposedtoyvvard the handles E andy F, with the blades B and rC inserted through the slot 14, as illustrated. Under this arrangement, the edges 13 exert a pressure vagainst the blades to cause the shearing or cutting edges G to properly coact With each other. By this action, itis obvious that the necessity of exreise-sz y .nai-rss sraiss raras? @ll-reines.

erting lateral pressure onV the handles to cause the shearing edgesG to properly coact, is obviated," and hence proper manipulation of the shears With either hand may be accomplished `Without of the user.

In the modified form of the' invention yillustrated in Fig. 5, one of the arms v11a of the body l0, is formed at its opposite ex-` -other similar shearing implements, comprisiiig means engaging over and exerting an inward pressure on the blades for causingV proper vcoactionof the cutting edges, said means consisting of astrip of resilient material cut, bent kand formed to provide a body of cross-sectional U-shaped configuration, including side arinsjoined by a .bight having a medial slot throughr which the blades extend.

' 2. An attachment for shea-rs, scissors, and

other similar shearing implements, comprising means engaging over and exerting an linward pressure on the blades for causing proper coaction of the cutting edges, said means consisting of a` strip of resilient'material cut,bent and formed to provide a body of cross-sectional U-shapedconfiguration, including side arms Joined by a bight lhaving a medial slot through Which the blades extend, the freeV edges of the side arms beingbovved longitudinally With-the concave sides disposed .toward each other.
